Similarities and Differences between the PS DRDP-R and the DRDP access

Beginning September 1, 2009, all new preschool-age children with Individualized Education Programs (IEPs) will be assessed only with the DRDP access. Many assessors who are experienced in using the PS DRDP-R would like to increase their knowledge of the DRDP access, either to complete the instrument in their role as a special educator, or to collaborate with the special educator in their role as child development teacher.

If you know how to use the PS DRDP-R, then using the DRDP access is easy. The chart below provides an at-a-glance comparison of these two instruments.
